To all whey/z. it m concern:

Be it known that I, FRANKLIN JACK- SON, citizen of the United States, residing at Berkele in the county of Alameda and State 0 California, have invented new and usefulImprovements in Apparatus for Submar1ne O' erations, of which the following is a speci cation.

My invention has reference to caissons adapted to be sunk in; the bottom of bodies of water for various kinds of submarine operations; and it consists in the peculiar construction the caisson, and in the novel combination and arrangement of parts.

It includes a novel method of suspending the. oaisson,'obviating the necessity of obstructive and lofty hoisting apparatus; an

e xtendible caisson that may be rapidly assembled and occupying small space when disassembled ;-an inner caisson which may be suspended within and raised or lowered inde endentl of outer caisson; and in various ot er deta' s of construction, as will be more fullyhereinafter referred to and shown in the drawings, in whieh-- Figure 1 is a plan or top view. Fig. 2 is 'a longitudinal view partially in section, on

line :c-ai Fi 1. Fig. 3 is a sectionof caisson with side broken. away, and showing inner caisson in operating position. Fig. 4 is a side elevation of side member of caisson;

- Fig. 5 is a top view of side member of cais- 4", 4'? .to a hoisting winch as at 5,

son:- Fig. 6 is asection of angle iron joint. Fig. 7 is a top view of. complete section. Figs. 8 and 9 are modified means for securing side and back plates. Fig. 10 is an elevation of back plate. Fig. 11 is a vertical view of back plate. Fig. 12 illustrates the joint between VGFtlCfi-lfllGlllbGlfS, showing the plate orbar 6 bolted across the junction of said members. I

" In the following description of construction and operation, the same number will be used to designate similar members in all views.

, A is 'afloat or ontoon, in which B is a the caisson C. I Said caisson is supported by chains or cables 3, 3', 3, extending from the lower or bottom caisson to ihe deck of float or pontoon A'; thence over sheaves as at 4,

draulic cylinder. The sup iorting chains or cable's 3|,-'-3P,=;1:eare preferab y secured to the or a. hy-

Fig. 2), said vertical members being of suflicient length to support two or more sections of the assembled plates forming the said .ca-isson C, al do showing two of the side members 7, 7 of the caisson, and the inner caisson in operative position.

In Fig. 2 the side of the float is broken away showing three assembled; sections of the caisson sus ended by means of the chains 3, 3, 3",- and t e inner caisson 8 is partially extended below lower caisson C, said inner' caisson 8 being supported by cables 22, passing over the upper cablesheaves 10, 10", and

thence to the lnner caisson hoisting drum 11,

Fi 4 shows construction of the side plate 7, wit exterior angle bars 12-42 riveted to top and bottom edges thereof, the outer turned flanges 13 strengthening the side members 7, and forming means of detachably connecting togetherthe plurality of sections by bolts extending through said flanges 13, as shown in sectional view, Fig. 7 also showv ing the securing lugs 14 riveted to the side plates 7 extending to detachably connect s de members 7 to vertical members 6, 6 by means of-through-bolt 15.

Fig. 5 is a top view of side members"! showing connecting flanges 13, securing lugs 14, 14:, and angular or curved four of the side plate 7 In Fig. 6 is shown a section of the joint, with connecting flanges 13 riveted to side plates 7, and through bolts 19.

'Fig. 7. is a top view of a complete section of caisson, showing side members 7', 7 back plate 16,- vertical members 6, 6, 6", with securing bolts 15 and 17, and connecting flanges 13,-a portion of one of said flanges broken awn to show the method of securing lugs 14:, am back plate 16.

In Figs. 8 and 9, the vertical members 6, 6, 6" are shown varied in form, and yet within the claims of this device.

Fig. 10 is an elevation of the back plate 16 showing angle bars 18 riveted to top and bottom edges thereof, and forming means of detachablyconnecting together a plurality of members 16 by means of bolts extending through said angle bars 18. V

Fig. 11 is a to View' of'back plate 1.6, angler bars 18. and olt holes 20.

1 vertical members by means of bars or plates 6 bolted across the junction of said members.

12 shows method of securely joining- I many multipLying pu The operation of the apparatus is as fol,- lows: The vertical nicn'ibers 6 are placed in position in well hole B supported by cables or chains 3, 3, 23 secured to the lower ends of said vertical members. The curved side sections 7 7 are bolted to said vertical members by means of the securing lugs 14, 14"; one section of back plate 16being secured to the vertical members 6, thus forming a complete extendible section of caisson pentagonal in form, said form adopted as ofleri'ng the least resistance to rapidly flowing cur rents or tides. The inner caisson 8, which is of smaller outside dimensions than 'outer caisson C- is suspendedby means of the supporting chains or cables 9 within caisson C. The assembled caissons are then ready to be lowered as required by means of the above described apparatus. Additional side and back sections are added as required. The vertical members 6 are extendible by means of additional lengths secured thereto as shown in Fig. 12.

The inner caisson G is of smaller outside dimensions than outer caisson C and is slidablewithin said caisson C permitting con- .tinuous operation while sections are beingadded to said outer caisson.

By the described constructionof the outer sections it will be seen thatalthiiugh pentagonal in form, only three vertical posts are required in construction, which thus considerably reduces the cost of construction.

The uide pulleys 30 over which the chains from t e outer caisson pass are so located that the chains from each of the three angles are brought parallel -to a common point where they are attached to a device 31, and

this device has a single connection with theyoke 32, or equivalent supportfor the pulley of the hoisting apparatus 5 so that a single rope from the hoisting apparatus, where as eys 32 as may be requ1red, serve to raise and-lower the outer caisson, with all portions moving in unison and vertically. The inner caisson being independently sus ended within the outer one, and having an independent hoisting mechanism, it-will beseen that this caisson ma be raised or depressed independent of the ot er,

and that operations may be continued within the inner caisson, while the outer one is being built up or extended to suit the requirements of the'work.

Having thus described my invention, what I claim and, desire to secure by Letters Pat eat is--- 1 In an apparatus for submarine operations, the combination with a float, of a-'-ver tical outer caisson su ported by chains or cables secured to the ottom memher'of said caisson and :extending to said float, and a suitable hoisting devi 2.
